Does your child have vision problems? Children learn through their eyes. Healthy vision is critical for children to see the computer and chalkboard, read, write, and even play. Children's eyes should be examined regularly, as many eye conditions and vision problems can be detected and treated early. Here are six signs that your child may have a vision problem.

1. Squinting eyes. If your child is nearsighted then squinting his eyes helps him make his vision a little clearer and can clear up any distorted vision. Nearsighted just means that they can see things that are near them but have a harder time with objects that are far away. Squinting is a coping mechanism to help relieve their blurry vision.

2. Sitting close to the TV. While it's a myth that sitting close to the television will damage your eyes, this habit may be a sign of a vision problem. If your child can't see televised images clearly or always holds a book too close, it could mean she or he is nearsighted.

3. Frequent eye rubbing. Yes, kids often rub their eyes when they're upset or tired. But if your child rubs her eyes while she's trying to concentrate on something, or while she is being active, it could mean that she has a vision problem. Frequently rubbing their eyes can be a sign of eye strain in children. It can be a sign of a focusing issue that causes the eyes to tire easily.

4. Losing place while reading. When children learn to read and are sounding out words, they will frequently use their finger to track which word they're on. But eventually children should be able to focus without losing their place. If after a while your child still uses his finger, ask him to try reading without pointing. If he has trouble, he may have a vision problem.

5. Sensitivity to light. Are your child's eyes sensitive to sunshine or indoor lighting? Many common eye conditions can make people more sensitive to light. If your child's light sensitivity is caused by an eye condition, then treatment for their condition can mean that his eye becomes less light sensitive.

6. Receiving lower grades. If your child is having a hard time seeing what her teacher writes on the board because of poor vision, she may not tell you about it. As a result, her grades can suffer. Most of what kids learn in schools is taught visually. That means if your child has an untreated vision problem, it could affect his or her development.

Yearly eye exams are as important as visits to the pediatrician. If you think your child may have a vision problem, schedule an appointment with a doctor. Early detection and treatment provide the best opportunity to correct a vision problem so your child can learn to see clearly.
